Die Kalibrierung multivariater Messinstrumente wie z. B. Spektrometer ist einfacher als in der Literatur üblicherweise suggeriert. In Finnland wird seit 2001 eine moderne Methode zur multivariaten Kalibrierung eingesetzt (Science Based Calibration (

A new method for multivariate calibration is described that combines the best features of “classical” (also called “physical” or “K-matrix”) calibration and “inverse” (or “statistical” or “P-matrix”) calibration. By estimating

Infrared detector arrays are very useful for spectroscopy to realize grating spectrometers with the ability for parallel signal detection. The signals from the detector pixels are usually very weak, and they have to be amplified. Because of the large
